SPECZFICATION forming part of Letters Patent No. '7 58,888, dated May 3,1904. Application filed October 28, 1903. Serial No. 178,850. No model.)

To all whom, it may concern.-

Be it known that I, VVILLIAM N. BARRETT, a citizen of the United States,residing at Somerset, in the county of Somerset and State of 5Pennsylvania, have invented new and useful Improvements in Joints, ofwhich the following is a specification.

This invention relates to joints; and it consists in certainimprovements in the construc- I tion thereof, as will be hereinafterfully described, and pointed out in the claims.

The object of the invention is to provide a joint which may be readilyassembled, especially with such shapes as it is not convenient I 5 touse a threaded joint, such sections of water-heaters, boilers,radiators, &c.

In the drawings the joint is shown between two ordinary fittings.

Figure I shows a section on the line 1 1 in Fig. 2; Fig. 2, a line 2 2in Fig. 1.

A fitting A has the opening A and the beveled shoulder a, surroundingsaid opening. As shown, the taper is on the outer periphery. The fittingB has the opening B and beveled shoulder I), surrounding said opening.The shoulders u and 6 form opposing tapered surfaces. Interposed betweenthe beveled shoulders o and!) is a metallic band (3, The bolts I) areprovided for subjecting the joint to pressure, so as to force theshoulders aand 1) into the engaging surfaces of the band C.

The band C is preferably of soft material, such as copper or brass, andcomparatively thin, so that it read ly shapes itself to the bev- 3 eledshoulders 11 and In this manner a perfect joint may be quicklyassembled.

It will be noted that the joint comprises as elements the fittings A andB and band C and that said parts (in the specific construction shown thefittings) are provided with opposing tapered surfaces struction on theband (1) forming continuous contacts to close the joint.

\Vhat l claim as new is 1. In a joint the combination of two fittings(as shown the shoulders u) and engag ng surfaces (mthe specific conl anda connecting-band, said parts being provided with opposing taperedsurfaces surrounding the opening in the joint and with I engagingsurfaces forming a continuous contact with the tapered surfaces to closethe joint. 2: In a joint the combination of two fittings and aconnecting metallic band, said parts being provided with opposingtapered surfaces surrounding the opening in the joint and with engagingsurfaces forming a continuous coni tact with the tapered surfaces toclose the joint. 3. In a joint the combination of two fittings j and aconnecting-band, said fittings being proi vided with opposing taperedsurfaces sur- 1 rounding the opening in the oint and said band beingprovided with engaging surfaces l forming continuous contact with thetapered l surfaces to close the joint. I a. In a joint the combinationof two fittings l and a connectin'gband said fittings being pro: videdwith opposing shoulders having their exterior surfaces tapered, saidshoulders surrounding the opening in the joint, and said band havingengaging surfaces forming continuous contacts to close the joint.

5. In a joint the combination of two fittings or parts to be connected;a metallic band, said fittings being provided with opposing taperedshoulders surrounding the opening in the joint and said band beingformed of material and of a thickness to shape itself to the taperedshoulder the tapered shoulder is forced against it.

6. In a joint the combination of the part A [having the tapered shouldera thereon; the

l part B having the tapered shoulder 1) arranged opposite the taperedshoulder (1, the thin metallic band C arranged on said shoulders andmeans for forcing said shoulders into said band.

In testimony whereof I have hereunto set my hand in the. presence of twosubscribing witnesses.
